If you have a bi-metal t-stat it will be plus or minus 10 degrees. If you have a digital t-stat it is accurate plus or minus 1 degree. You can adjust a bi-metal t-stat but not a digital. If it is the t-stat not keeping the right temp. then you will need to change it.

Tip

Keeping your whole home cool with central air.


Sometimes it is difficult to keep your home cool in the hot summer months. Also, some areas of your home may still be hot where other areas are too cool. Try this method to keep your home cool evenly throughout. Before you get started make sure your furnace filter is new. This will allow for maximum air flow.

If your living space is a single floor plan:

  1. Turn the air conditioning on
  2. Switch the furnace fan from auto to on.
  3. Measure the temperature in each room.
  4. Close the vents by about half in the cooler rooms
  5. This will force more cool air into the warmer rooms.
  6. Keep adjusting the vents until all the rooms have the same temp.

If your living space is on more than one level:

  1. Turn on the air conditioning.
  2. Switch the furnace fan from auto to on.
  3. On the lowest level of the house close half of the vents that are the closest to the stairs.
  4. This will force more cool air to the top floor where it is usually hotter.
  5. Cool air will sink from the upper floors which will keep the area near the stairs cool.
  6. Measure the temperature in all the rooms.
  7. Keep adjusting the vents until you have a nice even temperature throughout the house.
I found that leaving the furnace fan on all the time will keep your home evenly cool and comfortable. You may have to replace your furnace filter once a month due to the increased air flow. It will be well worth it in a cooler, more comfortable, and more energy efficient home.

Take Care,

I have an intertherm furnace model number 901282 and it will not heat my house when i turn on the thermostat it starts but just blows out cold air pleases help


The blower should come on after ignition occurs. When the blower comes on first ignition will not be activated as the thermostat signal shows the heat is on. This happens when the blower relay is stuck in the on condition

My furnace isn't heating my house. I was wondering if this was because there is a vent from my cold air duct to the outside thus drawing to much cold air into the system. Should this vent be closed in...


If this vent is connected to the return air duct line back to your furnace I would close it off. The only reason that I can see for having a vent to the outside is if you need more combustion air supply.Thank you.

Where is the re-ignite switch on a RUUD achiever 90 plus furnace?


Te flame symbol on the T-stat is just telling you that the T-stat is calling for heat.

What you need to do is go to the furnace and see if there is a blinking light. If there is count the blinks and look for a blink code list on the wiring diagram.(Usually found on the main panel.)

After you have done that, disconnect power to the unit, and then reconnect after a few minutes. This will reset any auto switches if they are tripped.

Chances are the problem will occur again even if the furnace does fire back up, but it "may" get you through the night until you can either diagnose the problem or get a service tech in.

Ideally, have someone else turn the power back on, and the thermostat, while you are watching the furnace to see exactly what is happening.

If it does not operate properly at that time, let me know exactly what it is/is not doing and we can go from there.

How do i operate thermostat and furnace


if your furnace is on 24 hours straight, before it heats up your home, then either your cold weather and indoor temps are extreme, or your unit is grossly undersized. if however your furnace cycles on and off when the temp is still way colder than you have set it you have either a bad stat that thinks its hotter than it is, or a bad furnace problem and even though the furnace is getting a signal from the stat to heat it is failing to do so. you'll have to watch and think this through to isolate the problem. if you set the furnace to max heat and it runs and heats the house reasonably quick then its probably going to be a bad stat. if you set it to max heat and it shuts off way before it gets to setpoint then the problem is in the furnace. be sure filters are clean, blower wheel is clean , returns are no obstructed, etc. if you by chance have an old mercury bulb stat they had a thing in them called a heat anticipator which basically worked like this. a dial with a little pointer determined how soon it would be till the furnaced reached the desired temp and anticipated how soon to shut off the burners in anticipation of the cool down period so you dont overshoot the desired temp. if these are bad or moved to different setting they can short cycle the furnace on of on off etc. or shut down the burner almost as soon as it lights. setting is usually at .4 to .6 on most, but really a digital stat is only way to go. by the way check to be sure you don't have a hot air supply grill blowing directly on the stat or it will shut off as soon as stat gets hot and rest of house will be cold. usual location is 5 feet off floor directly over the main return air grill or under it as the case may be. good luck

Carrier Furnace wouldn't light, fan was running all the time.


Most furnaces have a photo cell if it gets dirty the photo cell does not see a flame so it trips the reset button on flame failure.
